LOOSE-PULL E Y LUBRICATOR.

SPECIFICATION forming part of Letters Patent N0. 293,036, dated February 5, 1884.

Appllcaiion filed August 6, E83. (No model.)

To a/ZZ whom it may concern:

Be it known that I, LOUIS E. KANE, a citizen of the United States, residing at Cincinnati, county of Hamilton, State of Ohio, have 5 invented certain new and useful Improvements in Lubricators for Loose Pulleys, of which the following is a specification.

The object of my invention is a device for lubricating loose pulleys which can be cheaply produced and readily applied, and when ap-- plied will automatically supply the oil when the pulley is in motion, and automatically cut off the supply as soon as the pulley stops revolving.

\Vith these objects in view my invention consists of a cup or oil-reservoir, which is arranged in an inverted position with relation to the stem by which it is to be connected with the pulley-hub, so that the oil will be fed from the top of the cup or reservoir by centrifugal force when the pulley rotates.

It also consists in providing the reservoir with a movable yielding or flexible bottom, which will exert a pressure upon the bog of the oil in the cup when the pulley is in motion, and thus insure a steady feed of the oil to the shaft, and when the pulley stops will assume its normal position, and thus cause a partial vacuum, which will arrest the flow of oil from the discharge-orifice.

It also consists in certain details of construction and combination of parts, which embody the principle of my invention, all of which will be fully described in connection with the accompanying drawings, in which Figure 1 is a side elevation of a lubricator embodying my invention, and Fig. 2 is avie'w partly in side elevation and partly in central vertical section.

The upper part-,A, of the cup, which I prefer to make of glass, is fitted with a screwthreaded metal neck, 13, to engage an internal screw-thread in the cap 0. A flange projects from the inner end of the neck or tube 13, to 5 engage the inside of the cup A. The tube is held from turning by spurs upon the inside of the glass, which pass between ;slots in the flange of neck B. The upper end of the cup A has a groove or channel around the neck B, 50 to receive an elastic gasket, a, of cork or other A by a wire or cord, d.

riveting the shank down on the burr.

suitable material, which is pressed into the groove by the edge of the cap 0 when it is down, to make a tight joint. The bottom I) of the reservoir is made of rubber or other suitable elastic or flexible material, and is se- 5 cured around the rabbeted end of the glass cup In the lower center of the diaphragm D is aweight, g, which has a shank that projects through the shell D, to receive a burr, a. The weight is secured by The weight 9 should be heavy enough to compress or force in the end of the part D by centrifugal force when the pulley is running, and yet allow the part D to return to its normal posi- 5 tion should the pulley stop in a position that the oiler would be underneath the hub.

In the opposite sides of the cap 0 are secured two tubes, E, which curve around opposite sides of the reservoir, and have their opposite ends connected to the tapered screwthreaded stem or plug F, which is to connect the oiler to the "pulley-hub. These tubes reg ister with a longitudinal perforation in the stem F, (shownin dotted line, Fig. 2,)thus making the communication between the reservoir and discharge-port in the stem.

The parts 0 E F may be united in any con venient manner. In the drawings Ihave shown them united by screw-thread connection. The threads upon the opposite lower ends of the tubes E and in the opposite sides of the plug F are right and left, so that when the tubes are secured to the cap 0 their lower ends may be sprung apart to receive the plug F. The ends of the tubes are then drawn into the stem or plug by turning it around through the space tobe occupied by the reservoir, after which thereservoir A D is placed in position and screwed up until the edge of the cap forces the cork a into its groove, to make a tight joint. From one side of the stem F a transverse perforation extends inward and across the oil-duct. This is closed by a screw, f, which is for the purpose of regulating the supply of oil, or closing it ehtirely off, if desired.

It will be seen that when the pulley is revolving, the oil will be thrown by centrifugal force in the direction of the cap 0. The same force impcls the weighty from the axis of Iota- 10 tion, thus compressing the part D and forcing I the oil through the tubes E and oil-duct in the \Vhen the pulley is .again started, the air that has entered the reservoir will pass between the oil and the weighted end of the part D and act as a cushion to force the oil out through the tubes. Thus my device will accomplish its work so long as any oil remains in the reservoir. The reservoir is supplied with oil through an opening in the cap 0, which is stopped by a screw-plug, c.

It is evident that the form of my device may be varied without departing from the principle of my invention. For instance, the tubes E might be dispensed with, and, instead of them, a tube from stem F passedthrough. the part D up into the neck 13, or the upper part of the reservoir. The bottom part, D, could either be fitted to slide upon the tube, or the bottom of the part D could be drawn inward and secured permanently to the tube, and a follower put outside of the reservoir around the tube, which would force in the flexible bottom as the weight 9 does.

Vhat Iclaim as new, and desire to secure by Letters Patent, is-

1. In a lubricator for loose pulleys, the combination, substantially as specified, of the stem F and a reservoir having its discharge-orifice inverted with relation to the stem, with suitable means, such as shown, to connect the discharge-orifice with said stem.

2. In a loose-pulley lubricator, the combination of the stem F, tubes E, and cap C,with the inverted reservoir A B D, substantially as specified.

3. An oil-reservoir for loose-pulley lubricators, consisting, substantially as before set forth, of a rigid part, A, at one end, and terminating at its other end in atubular neck, B, and a flexible part, D, the open end of which is secured to the open end of the rigid part A, to form a single vessel.

4. The combination, substantially as speci fled, of the stem F, cap 0, and tubes E, with the rigid part A, neck 13, the flexible part 1), and weight g.

5. The combination, substantially as specified, of stem F, the curved tubes E, and cap 0, with a reservoir suspended from said cap, between the tubes, said reservoir having a weighted flexible part, D.
